Quentin Tarrentino's Star Wars?

For this synergy-based strategy (convergence) to be successful, media audiences must not simply buy an isolated product or experience, but rather, must buy it in prolonged relationship with a particular narrative universe, which is rich enough and complex enough to sustain their interest over time and thus motivate a succession of consumer choices.

In order for films to be truly successful in the greatest sense, it is no longer a matter of simply having a good run at the box office. A film must be something more than just the film. In other words, there must be many other entities surrounding it. Fans should be moved to buy the soundtrack, posters, video games, post comments online, and buy various memorabilia. It must become it's own phenomenon.
When the first Harry Potter book came out, it was just that, a book. However, as popularity grew and grew, it became an incredible phenomenon. Soon, there was a huge build up for the next book to come out, and then the next, and even the next. When a book does well, it is almost surely to be made into a film. As with The Davinci Code, The Chronicles of Narnia, and The Lord of the Rings, Harry Potter was made into a movie. Not only was it made into one film, but one for each book. Audiences not only await for the books, but for the films! Of course, soundtracks are sold in bulk, video games are sold along with all kinds of memorabilia.
It is quite incredible how quickly something can start in one section of media and quickly bleed into every other aspect of media. I find it interesting that the Harry Potter book covers were changed from their original cover to a cover with the actor who played Harry Potter in the movie. No longer is Harry Potter a book series, it is a complete and utter cultural phenomenon. Like those faithful to the Star Wars and the Lord of the Rings cult, those dedicated to all Harry Potter continue to be, and will be for years to come. Thus, much will continue to be bought and sold.
